Publication Metadata only Doğuştan Yarık Ayak ve Sindaktili Olgu Sunumu ve Literatürün Gözden Geçirilmesi(2022-11-06) VURAL Y.; EVİN N.; KOÇ C.; UZER G.; SARIKAŞ M.; EVİN, NUH; KOÇ, CAN; UZER, GÖKÇER; SARIKAŞ, MURATPublication Open Access The Stoppa approach versus the ilioinguinal approach for anterior acetabular fractures: A case control study assessing blood loss complications and function outcomes(2014-10-01T00:00:00Z) Elmadag, M.; Guzel, Y.; Acar, M. A.; UZER, GÖKÇER; ARAZI, M.; ELMADAĞ, NUH MEHMET; UZER, GÖKÇERBackground: The modified Stoppa approach was introduced to manage fracture of the anterior column instead of the ilioinguinal approach to reduce morbidity. However there is no clinical evidence to confirm its efficiency. Therefore this study was designed to ascertain: (1) if the Stoppa approach versus ilioinguinal allows less blood loss, (2) if functional and radiological results are superior to that of the ilioinguinal approach, (3) if the rate of complication was different.Publication Open Access Superior Mesenteric Artery Syndrome due to a Vertebral Hemangioma and Postpartum Osteoporosis following Treatment.(2015-01-01) Elmadag, M; GÜZEL, Y; UZER, GÖKÇER; TUNCAY, İBRAHİM; ELMADAĞ, NUH MEHMET; UZER, GÖKÇER; TUNCAY, İBRAHİMIn pregnancy, advanced vertebral hemangiomas may be seen, and these require treatment. The case reported here is of a 35-yearold female in the 32nd week of pregnancy who was admitted to the orthopaedics clinic with a history of backache and difficulty walking. A burst fracture of L1 associated with a vertebral hemangioma was identified with an L3 compression fracture secondary to osteoporosis. The local kyphosis angle between T12 and L2 was 27∘ . Kyphotic deformity was corrected and postoperatively, the measured T12–L2 local kyphotic angle was 9∘ . Twelve hours postoperatively, oral nutrition was allowed, but she developed nausea and vomiting and twenty-four hours postoperatively, an electrolyte imbalance developed. Postoperatively, the patient was diagnosed with superior mesenteric artery syndrome. To the best of our knowledge, this is the first reported case of superior mesenteric artery syndrome, which occurred following the correction of a kyphotic deformity that had developed secondary to an advanced hemangioma in pregnancyPublication Open Access Comparison of two types of proximal femoral hails in the treatment of intertrochanteric femur fractures(2015-09-01) Uzer, GÖKÇER; Elmadag, NUH MEHMET; Yildiz, FATİH; Bilsel, Kerem; Erden, TUNAY; Toprak, HÜSEYİN; UZER, GÖKÇER; ELMADAĞ, NUH MEHMET; YILDIZ, FATİH; BİLSEL, İSMAIL KEREM; ERDEN, TUNAY; TOPRAK, HÜSEYİNBackground: Hip nailing is frequently used to treat unstable intertrochanteric femoral fractures (ITF) in elderly patients. In this retrospective study, we compared the functional and radiological results, and the complications, of patients treated using proximal femoral nails (PFN) with an integrated, interlocking, compression lag screw, or two separate lag screws, which allow linear compression at the fracture site. Methods: A total of one hundred and eighteen patients were operated on for AO/OTA 31-A2 ITF between May 2010 and April 2012, and eighty-two of these patients, for whom sufficient follow-up data and documentation were available, were included into the study. PFNs with interlocking, integrated lag screws (Group I) were used in forty-four patients, and PFNs with two separate lag screws (Group II) in thirty-eight. Outcome parameters were the extent of varus collapse and leg length discrepancy on radiographs, and the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and Harris hip scores (HHS) as functional results. Results: Mean follow-up duration was 20 months (range, 12-36 months); fractures healed in all patients. Mean varus collapse values were 2.03±5.68° and 5.21±5.27° (p=0.01), Harris hip scores 73.2±11.65 and 74.72±11.15 (p=0.54), and WOMAC scores 70.78±11.41 and 71.78±11.19 (p=0.69) in Groups I and II, respectively. No difference was detected between the groups in terms of outcome parameters or complication rate. Conclusion: In the treatment of ITF, PFNs with an integrated, interlocking, compression lag screw, or two separate lag screws did not differ in terms of functional and radiological results or complication rate.Publication Open Access Safety of modified Stoppa approach for Ganz periacetabular osteotomy: A preliminary cadaveric study(2016-08-01T00:00:00Z) Elmadag, Mehmet; Uzer, GÖKÇER; Yildiz, FATİH; CEYLAN, Hasan H.; Acar, Mehmet A.; ELMADAĞ, NUH MEHMET; UZER, GÖKÇER; YILDIZ, FATİHObjective: The aim of this cadaveric study was to investigate the efficacy of the modified Stoppa approach in Ganz periacetabular osteotomy (PAO). Methods: The Ganz PAO was performed on 10 hemipelvises with normal hips, from 5 cadavers using the modified Stoppa approach through the Pfannenstiel incision. All of the osteotomies were performed under fluoroscopic control and direct visualizing the osteotomy site from the same incision. After the osteotomy, the acetabulum was medialized and redirected anterolaterally, and fixed with 2 screws. The neurovascular structures and the joints were examined by dissecting the soft tissues after fixation of the osteotomies. Outcome parameters were center-edge (CE) angle, the distances between the osteotomy and anterior superior iliac spine (ASIS), and between the osteotomy and the sciatic notch, neurovascular and joint penetrations. Results: After the osteotomy, the mean CE angle was improved from 19.8 degrees to 25.2 degrees, mean distance between the osteotomy and ASIS was 3.1 cm, and the mean distance between the osteotomy and the sciatic notch was 10.2 mm. The neurovascular structures and the joints were examined by dissecting the soft tissues after fixation of the osteotomies. No damage to the joint, surrounding arteries, veins or nerves was detected in any of the cadavers. Conclusions: Bilateral dysplastic hips can be treated with a 10 cm, cosmetically more acceptable incision in the same session using this approach. Quadrilateral surface of the acetabulum can be directly seen using this approach and the osteotomy can be safely performed. (C) 2016 Turkish Association of Orthopaedics and Traumatology.

This study explored the responses of bone and soft tissue to antimicrobialcoated screws. We investigated whether such screws, which have never been used to fix bony tissues, would result in a cytotoxic effect. We hypothesised that the coated screws would not be toxic to the bone and that the likelihood of infection would be reduced since bacteria are not able to grow on these screws. METHODS Titanium screws were inserted into the left supracondylar femoral regions of 16 rabbits. The screws were either uncoated (control group, n = 8) or coated with a polyvinylpyrrolidone-polyurethane interpolymer with tertiary amine functional groups (experimental group, n = 8). At Week 6, histological samples were obtained and examined. The presence of necrosis, fibrosis and inflammation in the bony tissue and the tissue surrounding the screws was recorded. RESULTS Live, cellular bone marrow was present in all the rabbits from the experimental group, but was replaced with connective tissue in four rabbits from the control group. Eight rabbits from the control group and two rabbits from the experimental group had necrosis in fatty bone marrow. Inflammation was observed in one rabbit from the experimental group and five rabbits from the control group. CONCLUSION Titanium surgical screws coated with polyvinylpyrrolidone-polyurethane interpolymer were associated with less necrosis than standard uncoated screws. The coated screws were also not associated with any cytotoxic side effect.Publication Metadata only Cavus Foot Deformity with Calcaneonavicular and Medial Cuneiform–Navicular Coalition: A Case Series(2023-01-01) İNCESOY M. A.; UZER G.; ORUJOV S.; Geckalan M. A.; ŞENARAN H.; İNCESOY, MUSTAFA ALPER; UZER, GÖKÇER; ORUJOV, SAİD; ŞENARAN, HAKANTarsal coalitions have only very infrequently been observed in the context of cavus foot abnormalities. Recognizing this diagnosis could be crucial to effective cavus repair. We report tarsal coalitions observed in cavus deformity here. Between 2022 and 2023, the records of every patient treated by one of the authors for a varus deformity who was later determined to have either a unilateral or bilateral tarsal coalition were examined. Two patients with cavus deformities who were treated by one of the authors have either a unilateral or bilateral tarsal coalition. Three foot (medial cuneiform–navicular n = 1 and calcaneonavicular n = 2) with tarsal coalition were examined. All of these cases occurred in patients with idiopathic cavus deformity. Computed tomography scans were used to make a firm diagnosis for each patient. We advise surgeons to keep an awareness for this potential comorbid issue in all cavus foot abnormalities and to take advanced imaging into consideration. In these uncommon cases, the medial cuneiform–navicular and calcaneonavicular joints formed an osseous coalition with pes cavus deformity, which successfully resolved with conservative and surgical treatment, respectively. Level of Clinical Evidence: IV.Publication Metadata only Surgical Management and Outcomes of Patients with Idiopathic Peroneal Spastic Flatfoot A Retrospective Case Series(2023-01-01) UÇAN V.; DEMİREL M.; ALIYEV O.; YILDIZ F.; UZER G.; UÇAN, VAHDET; ALIYEV, ORKHAN; YILDIZ, FATİH; UZER, GÖKÇERBackground: Although tarsal coalition represents the most common cause of peroneal spastic flatfoot, its existence cannot be verified in several cases. In some patients with rigid flatfoot, no cause can be detected after clinical, laboratory, and radiologic examina-tion, and the condition is called idiopathic peroneal spastic flatfoot (IPSF). This study aimed to present our experience with surgical management and outcomes in patients with IPSF.Methods: Seven patients with IPSF, who were operated on between 2016 and 2019, and followed for at least 12 months were included, whereas those with known causes, such as tarsal coalition or other causes (eg, traumatic) were excluded. All patients were followed up for 3 months with botulinum toxin injection and cast immobilization as a routine protocol, and clinical improvement was not achieved. The Evans procedure and grafting with tricortical iliac crest bone graft in five patients and subtalar arthrodesis in two patients were performed. The American Orthopaedic Foot and Ankle Society ankle-hindfoot scale scores and Foot and Ankle Disability Index scores were obtained preoperatively and postoperatively from all patients.Results: On physical examination, all feet manifested rigid pes planus with varying degrees of hindfoot valgus and limited subtalar motion. Overall, the mean American Orthopaedic Foot and Ankle Society and Foot and Ankle Disability Index scores significantly increased from 42 (range, 20-76) and 45 (range, 19-68) preoperatively (P = .018) to 85 (range, 67- 97) and 84 (range, 67-99) (P = .043) at the final follow-up, respectively. No major intraoper-ative or postoperative complications were observed in any of the patients. All computed to-mographic and magnetic resonance imaging scans revealed no evidence of tarsal coalitions in any of the feet. All radiologic workups failed to demonstrate secondary signs of fibrous or cartilaginous coalitions.Conclusions: Operative treatment seems to be a good option in the treatment of patients with IPSF who do not benefit from conservative treatment. In the future, it is recommended to investigate the ideal treatment options for this group of patients. (J Am Podiatr Med Assoc 113(1), 2023)Publication Metadata only Treatment of Congenital Deformities of Cleft Foot and Syndactyly: A Case Report and Review of the Literature(2024-04-01) EVİN N.; VURAL Y.; KOÇ C.; UZER G.; EVİN, NUH; VURAL, YASİR; KOÇ, CAN; UZER, GÖKÇERCleft foot is a rare congenital anomaly characterized by a central conical defect and deficiency of the foot rays. Syndactyly is the fusion of the skin with or without the bone of adjacent digits, and it may be associated with syndrome‑related cleft foot. The aim of the treatment of cleft foot and syndactyly is to obtain a normal form and function by closing the cleft defect, obtaining symmetrical and cosmetic feet, allowing patients to wear normal shoes comfortably, and preventing collapse and angulation deformities of the toes. In this study, the treatment of congenital cleft foot and syndactyly coexistence is presented, and it is demonstrated that excess skin after soft‑tissue syndactylization of the cleft foot can be used to reconstruct syndactyly defects.
